Experimental example 1: dissolution test
The capsules of examples 1 to 11 and comparative example 1 were subjected to dissolution measurement according to the second method (paddle method) of dissolution measurement in the chinese pharmacopoeia 2020. A dissolution test was carried out using 900ml of a 0.1N (normality) hydrochloric acid solution as a dissolution medium at 37. + -. 0.5 ℃ and a rotation speed of 50 rpm. The dissolution data are shown in tables 9 and 10.

Compound a was not completely dissolved in example 7 (calcium phosphate), example 8 (calcium citrate), example 10 (calcium gluconate) and example 11 (calcium hydrogen phosphate + anhydrous sodium carbonate), and gelation occurred during dissolution. In comparative example 1, the compound A dissolved out in 15min only to 80% or more.
Experimental example 2: stability study
The capsules of examples 1 to 5, 6, 9 and 1 were placed in an atmosphere of 40 ℃/75% RH for six months, and the formation of degradation products was measured by HPLC. The stability data are shown in tables 11, 12 and 13.
